Objective To investigate the content of tea polyphenols, catechins, and caffeine in novel-tea beverages available on the market. Methods This study collected and analyzed total of 46 samples from 17 different brands in the market. These products were categorized and compared into 3 types: Novel-milk tea beverages, novel-blended tea beverages and novel-pure tea beverages. Results The findings revealed that the average volume of these was 566 mL per cup. Comparison of average prices of 3 different kinds of new tea drinks was as follows: Novel-milk tea beverages>novel-blended tea beverages>novel-pure tea beverages. In terms of chemical composition, the content of tea polyphenols, catechins, and caffeine in novel-milk tea beverages were significantly lower compared to those in novel-blended tea beverages and novel-pure tea beverages. Notably, the content of tea polyphenols and catechins were influenced by the type of tea base used in the novel-tea beverages. In this study, green tea bases were characterized by tea polyphenols content exceeding 1000 mg/kg and catechins content exceeding 400 mg/kg. Conclusion This research can enable consumers to understand the specifications, prices and tea component content of novel-tea beverages on the market, and also provide assistance for product research and development of novel-tea beverages.
